    if the system is at lower temperature... rise in temperature increase entropy but if the system is already at high temperature entropy not increase much. I am attaching a paragraph from ncert

    'ds' in the equation is not entropy, it's the change in entropy. Entropy will increase with temperature but 'the change in entropy' decreases.

    If you increase temperature, you increase entropy. (1) More energy put into a system excites the molecules and the amount of random activity. (2) As a gas expands in a system, entropy increases. This one is also easy to visualize.
